Tl SISSL prides which functionary when a web browser connects to web site using the HTTPS protocol?

TLS/SSL performs a handshake that negotiates cipher suites and authenticates the server via a digital certificate, then encrypts all data exchanged between the browser and server. This combination of encryption, authentication, and integrity checking is precisely what 'delivering secure communication over a network connection' means in the context of HTTPS.

TLS/SSL does not protect the web server from being compromised - server security depends on patching, access controls, and hardening, not transport-layer encryption.

While TLS encrypts packets so intercepted traffic is unreadable, this is a mechanism of secure communication rather than a separate or distinct function from answer A.

TLS/SSL has no capability to detect or block malware downloads - that responsibility belongs to antivirus software, browser content filters, or endpoint protection tools.
